The property is evaluated when acceptance for loading of solid bulk cargoes is judged prior to shipment. The liquefaction can be prevented by means of limiting the moisture content of the cargo by introducing the safety margin, regardless of the condition of stresses. It is rational to limit the moisture content of cargoes, which may liquefy, because liquefaction is not liable to occur when the degree of saturation is low, even if the permeability of the material is low. To prevent sliding and shifting of ore concentrates in storage biodegradable thermoplastic materials were added to the ore. The polymer absorbs water from the particle pore in mineral concentrates and its moisture content goes down. In consequence, polymer prevents: drainage of water from the particle pore, sliding and shifting of ore concentrates in storage

Transport of mineral concentrates is associated with high risk of liquefaction of the cargoes. This type of goods containing water may liquefy and shift dangerously across the cargo compartments. Therefore, it is rational to limit the moisture content of the cargoes which may liquefy. To prevent sliding and shifting of ore concentrates in storage biodegradable materials composed of starch are added to the mineral concentrates. The influence of adding starch materials to the mineral concentrates on its parameters determining ability for safe shipment was assessed on the basis of determination of the following parameters: permeability, cohesion and internal friction angle of concentrates

Sector competitiveness does not constitute a simple sum of factors identified on different levels of economic analysis. It turns out that competitiveness is determined by both measurable and non-measurable factors. A growing influence of behavioural factors inclines to undertake aggregate research attempts of a qualitative nature. The authors of this paper have made an effort to confront the price and non-price factors of competitiveness based on a specific sector of economy, i.e. the round wood market in Poland.

INTRODUCTION: We have previously shown altered expression and/or intracellular distribution of selected synaptic proteins that may contribute to neurological dysfunction observed during acute liver failure (ALF) in mice. During ALF an increased level of TGF‑β1 in the serum and brain was also observed. Moreover, neutralization of TGF‑β1 appears to improve the neurological score of ALF mice. AIM(S): We test the hypothesis that thrombospondin(s) – related activation of TGF‑β1 may affect the expression of NR1, a major NMDA receptor subunit. METHOD(S): We measured total and active TGF‑β1 level in the brain and blood of C57Bl6 mice with ALF induced by single i.p. injection of azoxymethan (AOM; 100 mg/kg of b.w.) and after neutralization of TGF‑β1 induced by single i.p. injection of ab‑TGF‑ β1 (1 mg/kg) 2 h before AOM injection. In addition we analyzed the expression of thrombospondin-4 (Thrb4) and NR1 subunit in AOM brain homogenates and membrane/cytosolic fractions. RESULTS: In ALF mice, active form to total TGF‑β1 ratio was increased by ~35%,and ~30% in serum and rain cortex, respectively. Expression of Thrb4 was increased by ~30% in homogenates and by ~35% in cytosolic fraction. Both, AOM injection and TGF‑β1 neutralization induced the increase of NR1 subunit in membrane fraction, by ~40%, and ~60% respectively. CONCLUSIONS: The results indicate that in ALF mouse, neutralization of cytokine TGF‑β1 may cause an increase in NR1 expression, the effect not potentiated by AOM. The increase in the expression of Thrb4 play a potential role in the activation of TGF‑β1, as may be assumed from the increase in TGF‑β1 ratio in the serum and the brain homogenates. The particular mechanism requires an additional research. FINANCIAL SUPPORT: Supported by the grant Prelludium10 2015/19/N/NZ5/02249 and the Leading National Research Centre (KNOW).

A two-year pot experiment was conducted to estimate the effect of liming and application of waste materials on the yielding and on the content of certain nutrients in cock’s foot (Dactylis glomerata) grown at increasing doses (75, 150, 225 mg kg-1) of nickel in the soil. It was demonstrated that all the factors studied determined the yielding of the plant. A negative effect of nickel was observed, especially in the 1st year of the experiment, manifested in an inhibition of the growth and development of the test grass, mainly in treatments without liming. In treatments where lignite was added to the soil in the 1st year of the experiment, the toxicity of nickel was lower than in treatments with an addition of straw. In the 2nd year of the experiment no yield of cock’s foot biomass was obtained from those no-liming treatments in which the content of nickel was the highest. Liming had an effect on the content of nitrogen, phosphorus and sulphur in cock’s foot biomass, especially in the 2nd year of the experiment. The levels of those macroelements were somewhat higher in treatments with an addition of lignite compared to those with rye straw.
